A fund screening logistics warehouses, a bank reviewing loan collateral, a developer looking for land or a portal enriching its listings all hit the same wall: the official data on a Spanish plot exists, but it's spread across a dozen public bodies, in different formats, with no easy way to query it at scale. That's why we built the Hogarfax Site Report API: send a cadastral reference or a pair of coordinates and get back an analysis of that plot, ready for your systems.

1 request
per plot: cadastral reference or coordinates
15
hazard and constraint assessments with a consistent status
JSON + PDF
to plug into your platform or hand to a client

What you get back

  • Plot identity: cadastral reference, address, use, areas, year built, units and geometry.
  • Buildings: footprint, floors and gross floor area.
  • Natural hazards: river and coastal flooding, wildfire, seismic hazard and radon, among others.
  • Land and constraints: planning classification, water and coastal public domain, livestock trails, high-voltage lines and nearby industrial sites.
  • Connectivity: distance to the nearest major road, railway line and electrical substation. Essential when you're looking for logistics or industrial land.
  • PDF report with the same content, ready for an investment committee or a client.

Each assessment comes with a clear status (clear, caution or alert) plus the measured facts behind it: distances, official names, land classes. So you can filter a portfolio of hundreds of plots down to the ten worth visiting.

Who it's for

  • Funds and asset managers screening sites before commissioning full due diligence.
  • Banks and servicers reviewing the physical risk of a collateral portfolio.
  • Developers assessing land: classification, constraints and access in one call.
  • Valuers who want to attach the plot's risk context to every valuation.
  • Portals and proptech that want official data on their listings without maintaining the datasets themselves.
  • Insurers underwriting by address who need to know what's around it.
A real use case: screening a list of logistics warehouses and plots. With one call per site you know whether it's in a flood zone, how the land is classified, whether any easement crosses it, and how far it is from the motorway and the substation. What used to take days of manual lookups per plot becomes a spreadsheet ranked by priority.

How it works

It's a REST API with key-based authentication. You request a report, the API immediately returns an ID and, within seconds, the result is ready to fetch. Requesting the same plot twice isn't charged twice. The documentation includes the full OpenAPI specification, so your developers can integrate it in an afternoon.

The data comes from official public sources (the Spanish Cadastre, the Ministry for the Ecological Transition, the National Geographic Institute, the Nuclear Safety Council and the regional governments, depending on the check), and every report states which public body each data point comes from. Nothing is inferred from photos or satellite imagery: it's all auditable.

Shaped around your needs

Not every client needs the same thing. We can adjust which fields you receive, the input format (single references, lists or coordinates) and the output, and even brand the PDF. Pricing depends on the number of plots analysed.

Try the API on your own plots

The API is private. Tell us about your use case and we'll give you trial access with a limited number of requests, so you can see the output on your own data.
